Change NFC ndef values in softwarehttps://devzone.nordicsemi.com/f/nordic-q-a/37244/change-nfc-ndef-values-in-softwareHi, I&#39;m trying to edit the nfc message in software but after a while the nfc stops working. What could I be doing wrong? This is my code, I change the value every second and update the ndef file. Thanks!

When i don&#39;t have a variable datalength.</p><div style="clear:both;"></div>RE: Change NFC ndef values in softwarehttps://devzone.nordicsemi.com/thread/143673?ContentTypeID=1Fri, 10 Aug 2018 07:57:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f4140fef-1670-4a31-9228-4911fc27c271Joakim Jakobsen<p>Hi!</p> <p>So your application is working as expected for a while, before running into some error?<br />Have you tried debugging to figure out what is causing the NFC to stop working?</p> <p>I didn&#39;t find any obvious mistakes or errors from reading your code.</p> <p>Did you take a look at the NFC examples in our SDK?<br />The <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/nfc_writable_ndef_msg.html?cp=4_0_0_4_7_6">Writable NDEF Message Example</a> should be relevant for you.</p> <p>Best regards.</p> <p>&nbsp;</p><div style="clear:both;"></div>
